fix: check for workbench-dev role in addition to group

[bodom0015]

Problem

Sometimes Keycloak Groups aren't mapped properly?

Unclear if this is due to configuration error, or something else

Approach

• fix: fallback to checking Role name (in addition to group name)

How to Test

1. Checkout and run this branch locally (see workbench-helm-chart)
2. Navigate to https://kubernetes.docker.internal/ (ignore browser certificate warnings)
3. Login/register with Keycloak
   • You should be brought back to the Workbench, now logged in
4. Edit your user in Keycloak to have the workbench-dev role (optionally, without the group)
5. Add an application from the "All Apps"
   • You should be brought to "My Apps" to see your new app
   • You should see an "Edit" (pencil) icon beside the Launch button
6. Click the Edit button
   • You should see the "Edit Service" page loads
   • You should see this offers you a way to set custom envvars for the application
